Prince William and Kate Middleton have revealed they are "delighted" to be expecting their third child in April.

A statement reads: "Their Royal Highnesses The Duke and Duchess of Cambridge are delighted to confirm they are expecting a baby in April 2018."

Kate has been suffering from hyperemesis gravidarum - a severe form of morning sickness - but made a surprise appearance at a royal engagement on Monday, and is due to visit Norway and Sweden with the Duke on an official visit early in 2018.

Kensington Palace announced news the couple were expecting their third children earlier last month but did not reveal when the baby would be due.

Their first child, George, was born in July 2013 who was followed by a daughter, Charlotte, in May 2015.

Their offspring's names are plucked from a very small pool of regal ones, they're enrolled at the same high-rent schools their royal relatives attended, and their tender, formative years are plotted with military precision.

It's on this matter the Duke and Duchess of Cambridge are rebelling, albeit very gently, reports the Mirror.

So while George has only just started school, and has at least eleven more years of formal education to go (hang on in there, mate), his parents have reportedly already made a decision about his secondary education.

And they're breaking with tradition.

Unofficially, senior members of the royal family have all attended same-sex boarding schools, such as Eton and Gordonstoun.
